ATTACHMENT FOR COTTON-CONDENSERS.

SPECIFICATION forming part of Letters Patent No. 779,635, dated January 10, 1905.

Application filed July 20, 1904. Serial No, 217,406.

To (all whom t may concern:

Be it known that we, OLEMENTS A. BROWN and AMAsA ST. ONGE, citizens of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Attachments for Cotton- Oondensers.- of which the following is a speciiication.

In a cotton-condenser machine which has two'screen-cylinders located one above the other and a suction-fan beneath said cylinders it frequently happens that the air-draft created by the fan will cause the cotton-lap to adhere more-firmly upon the peripheral surface of the lowermost screen-cylinder by reason of this cylinder having' closer connection with and receiving' a much stronger draft than the uppermost screen-cylinder. The result is that a split is formed in the cotton-lap, and this imperfect portion of the lap has to be discarded and reworked over again.

The object of our invention is to provide means for guiding the cotton-lap free from the surface of the lowermost screen-cylinder until it reaches a point between both said screen-cylinders, so that splitting of the lap is prevented.

In the accompanying sheet of drawings, Figure l represents a perspective view of our improved attachment for a cotton-condenser machine. Eig. 2 is a partial longitudinal section of a cotton-condenser machine as operating upon a cotton-lap, and also showing the normal position of our attachment on said machine. Fig. 3 is an enlarged cross-sectional detail view of our attachment as secured upon the machine-frame. Fig. 4 is a perspective view of a split cotton-lap.

Like characters indicate like parts.

A designates our improved attachment as designed for a cotton-condenser machine. This attachment consists of a wood rail b and a series of wires c c, which are curved in the form of an arch. Each of the wires c c is held in a rigid position on the rail by having one of its ends bent U-shaped, as at c, in Fig. 3, and which bent portion of each wire that the air-draft created by the suction-fan will pass through them. This air-draft passes through casings located at each end of said cylinders ff, as at m, in the direction indicated by the arrows in Fig. 2.

In the ordinary working of the cotton-lap the air-suction is somewhat greater in the lowermost screen-cylinder by reason of this cylinder being closer to the fan than that of the next or uppermost cylinder, so that as the cottonlap (designated by reference-letter i) passes between both screen-cylinders in its movement from the beater to the calender-rolls it is caused to adhere more firmly against the surface of the lower cylinder. Thus a split takes place in the thickness of the lap, as at a" in Fig. 4.

Our attachment is applied directly in front of the lower screen-cylinder and is secured in a fixed position upon a portion of the machineframe 7' by screws It in the manner shown in Fig. 3. I

This attachment is designed to have the upper ends of its wires c c terminate close to a point where the cotton-lap enters between both screen-cylinders, and from this point the wires are curved outwardly, so as to form a clearance, as at Z, in order to prevent too strong an air-suction from the lower cylinder until the lap reaches said point between both cylinders. In this way the air-draft is equalized upon each surface of the lap, whereby the same is caused to feed regularly and without any split taking place in its thickness.

This 'attachment contains in itself all that is necessary to afford an effective means to preventa lap from splitting during its feeding movement in a cotton-condenser machine and at the same time an attachment that is inexpensive to manufacture.

What we claim, and desire to secure by Letters Patent, is-

l. The herein-described attachment for a cotton-condenser machine, consisting of a rail having a series of wires rigidly secured thereto and each of said wires curved so as to form an arch, substantially as shown and for the purpose specified.

2. In a cotton-condenser machine having two screen-cylinders situated one/over the other and a suction-fan arranged to produce an air-draft through said cylinders, the comhin ation therewith, of an attachment designed to be secured upon the machine-frame and lo- CLEMENTS A. BBOVN. AMASA ST. ONGE.
